LAB ONE: Exercise 4 – Endocrine System Activity 1: Metabolism and Thyroid Hormone Part 1: 1. The normal rat had the fastest basal metabolic rate. 2. The metabolic rates differed between the normal rat and the surgically altered rats because the surgically altered rats didn’t have a thyroid or pituitary gland and therefore‚ the normal rat had a faster basal metabolic rate. The results turned out to be the way I predicted them to be. 3. T3 and T4 would be missing in the animal’s blood

NAME LAB TIME/DATE _ Endocrine System Physiology: Computer Simulation Metabolism The following questions refer to Activity 1: Determining Baseline Metabolic Rates. 1. Which rat had the fastest baseline metabolic rate? -------------------------The normal rat 2. Compare the baseline metabolic rates for the thyroidectomized rat and the normal rat and explain your results. The thyroidectomized rat had a lower baseline metabolic rate beause the removal of its thyroid gland prevented it

Preschool began in Europe during the 1800s when European educators commenced education systems with young children in mind. They did this with the aim of aiding kids throughout one of the most critical junctures of child development(History).

reaction to stress recognizes there’s a danger and prepares to deal with the threat‚ a.k.a. the fight or flight response. Activation of the HPA axis‚ the nervous system (SNS) and the adrenal glands take place. During this phase the main stress hormones cortisol‚ adrenaline‚ and noradrenaline‚ is released to provide instant energy. If this energy is repeatedly not used by physical activity‚ it can become harmful. Too much adrenaline results in a surge of blood pressure that can damage blood vessels of

Cortisol helps maintain blood pressure and cardiovascular function‚ slows immune systems inflammatory response‚ breaks down sugar for energy (balancing insulin levels) and helps regulate metabolism of proteins‚ carbohydrates and fats. The brains hypothalamus glands control and accurately balance the amounts of cortisol needed. Symptoms of

Abstract This review focuses on the possible factors that play a role on the development of psychological disorders such as genetic‚ biological and environmental influences whereby genetic influence involve the imbalance of neurotransmitters that prevent individual’s brain from functioning efficiently as compared to healthy individuals whereas biological influences such as cognitive deficits that impaired partial brain functions of individuals while environmental influence does not directly relates

Cortisol is a natural steroid hormone produced by the adrenal glands and performs several important functions. The release of cortisol is stimulated by the pituitary gland found inside the brain. Cortisol‚ also referred to as the stress hormone is responsible for cardiovascular function‚ the regulation of blood pressure and sugar in the blood. Cortisol is the main
